    摘要: Systems, methods, and devices for determining neutron-gamma density (NGD) measurement of a subterranean formation that is accurate in both liquid- and gas-filled formations are provided. For example, a downhole tool for obtaining such an NGD measurement may include a neutron generator, neutron detector, two gamma-ray detectors, and data processing circuitry. Neutron generator may emit neutrons into a formation, causing a fast neutron cloud to form. Neutron detector may detect a count of neutrons representing the extent of the neutron cloud. Gamma-ray detectors may detect counts of inelastic gamma-rays caused by neutrons that inelastically scatter off the formation. Since the extent of the fast neutron cloud may vary depending on whether the formation is liquid- or gas-filled, data processing circuitry may determine the density of the formation based at least in part on the counts of inelastic gamma-rays normalized to the count of neutrons.

    摘要: A method of determining the density of an underground formation surrounding a borehole from measurement of gamma rays arising from irradiation of the formation by a nuclear source in a tool body located in the borehole, and measurement of gamma-ray flux in the tool body at two different detector spacings from the source, the method comprising determining a substantially straight-line relationship between gamma-ray flux measurements at each different spacing with respect to the density of the formation for a tool body with no standoff; determining a relationship defining the deviation with respect to tool standoff of the density determined from the measured gamma-ray flux measurements at the two different detector spacings from the density calculated from the straight line relationships; and for a given pair of gamma-ray flux measurements at the different detector spacings, determining the intersection of the relationship defining the deviation with the straight line relationship so as to indicate the density of the formation surrounding the bore-hole; wherein the source is a neutron source and the gamma rays measured in the too! body are neutron-induced gamma rays resulting from neutron irradiation of the formation.

    摘要: A method of changing from a first gear position to a second gear position of a transmission arrangement is disclosed. The arrangement includes a rotatable transmission member, a hydrostatic continuously variable transmission coupled to the transmission member and operable to rotate the transmission member at a first speed, a controller configured to control operation of the hydrostatic continuously variable transmission, and a gear apparatus coupled to the transmission member and configured to be shiftable between at least the first gear position and the second gear position. The method includes controlling the hydrostatic continuously variable transmission, using the controller, to rotate the transmission member at the first speed, and shifting the gear apparatus from the first gear position to the second gear position while the transmission member is rotating at, or converging with, the first speed.

    摘要: A primary or secondary game for a gaming device. In one embodiment, the player is provided up to three picks, i.e., picks three contestants. The first two contestants both form potential award offers. The game then provides the greater of the two potential award offers to the player as an initial offer. This initial sequence alternatives includes more than two picks, contestants and potential offers. The offer acceptance feature arises after the initial offer. The player must decide whether to keep the initial offer or forego that offer for a final offer. If the player keeps the offer the game provides that initial offer to the player and ends if the player rejects that initial offer, the game proceeds to build a third and final offer, which is then provided to the player automatically.

The method provides for improved target detection the presence of clutter.
